IMPROVEMENT IN PLASTERlNG BOARDs FOR WALLS.

Specification forming part of Letters Patent No. 14?,904, dated February 24, 1874,- application filed August 21, 1873.

To all whom it may concern:

Be it known that I, JUDD M. COBB, of Beloit, in the county of Rock and State of NVi'scousin, have invented a new and useful Improvement Plastering Board or-Paper; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings forming part of this specification, in which- Figure l is a perspective view of a roll or sheet of plastering-board faced with wall-paper, and showing the edges of the latter turned back from the board. Fig. 2 is a perspective view of a roll or sheet of wall-paper.

Similar letters of reference in the accompanyin g drawings denote the same parts.

Plastering board or paper consists in a thick, strong paper made in continuous lengths from straw, or from straw and stock, and rendered fire-proof or damp-proof, or both, by any suitable treatment, or left plain and untreated as it comes from the paper-machine. It is designed for use as an economical substitute for laths and plastering by being nailed directly to the studdin g of a room upon the walls and ceiling, and when faced with wall-paper of any kind, it forms a cleap and complete substitute for laths, plastering, and wall -paper. The principal objection to the employment of this board for the purposes above named con sists in the difficulty of finishing the joints as they meet upon the studdin'g. The edges are secured to the studding by nails, the heads of which are either exposed to view, and, to-

gether with the joints, present an unsightly appearance or the jolnts and nail-heads are covered. with a narrow strip of paper or cloth,

which cannot be cut and applied to match the adjoining patterns of wall-paper. My invention has for its object to overcome this objection, so that the joints of the boards as well as the nail-heads shall be covered by the wallpaper itself, and the pattern of the latter perfectly matched. To this end the invention 0011- sists in pasting the wall-paper upon the board with the edges of the former turned back a short distance from the edges of the board, so that the nails may be driven through the latter and the edges of the wall-paper pasted down over the joints and nail-heads. In this manner the nailheads and joints are covered and the pattern of the paper matched so as to form a surface of regular figures.

In carrying out my invention, I take the wall-paper A, of the'requisite size and preferred pattermand paste or otherwise apply it to the face of the plastering-board B, as shown in Fig. 1, leaving the edges 0 of the paper unpasted or unfastened. The wall-paper is usually formed with the waste margins D, which may be cut off from one side, either before or after the paper is attached to the board.

In applying the faced board to a wall or ceiling, it is first nailed to the studding along the edges, and the uncut flap or strip of wallpaper pasted down over the joint and nailheads. The cut flap or strip is then pasted down over the first flap to match the pattern of the paper.

If desired, the wallpaper may be trimmed upon both edges before pasting; but I prefer to trim one edge only, as above described.

Inasmuch as the studding of buildings is usually arranged with the studs sixteen inches apart from center to center, I make the faced board sixteen or thirty-two inches in width, for convenience of application. It may be made wider or narrower, however, to correspond with different arrangements of the studding.

Having thus described my invention, what I claim is 1. Plastering-board prepared with a facing of wall-paper so applied that the edges of the latter shall form loose flaps or strips at the edges of the board, substantially as described, for the purpose specified.

2. The plastering-board provided, as described, with a facing of wall-paper, when applied to the studdin g of a building for the purpose of covering the nail-heads and jointsof the board and matching the pattern of the paper, substantially as setfort J UDD M. COBB.
